A laser driver capable of driving over 100 mA modulation current fabricated in 0.35/spl mu/m SiGe BiCMOS process was presented in this work. Measurements on mounted chips show clear electrical eye diagrams over 14-Gb/s data rate with a typical (20% to 80%) 24 ps rise time, 26 ps (20% to 80%) fall time, and a jitter (RMS) less than 2 ps. Moreover, optical eye diagram is also demonstrated by connecting the driver with a commercial 10-Gb/s 1310-nm laser diode and it stays well within the 10-Gb/s Ethernet transmitter mask.
